Electronic Pinion Factor (98 Only)

The nature of the Electronic Pinion Factor requires that certain features must be taken into consideration:
- If no pinion factor is stored in an installed TOM, the vehicle speedometer will not indicate speed when moving
- Selecting the wrong final drive ratio or tire size may cause the speedometer accuracy to fall out of specification

Use the following procedures to set the electronic pinion factor using the DRB Scan Tool:
- Select "Transmission" system, then "Miscellaneous" functions, then "Pinion Factor". The DRB will display the current tire size.
- If the tire size is incorrect, depress the Enter key and then select the correct size.
- Depress the Page Back key to exit the reset procedure.

NOTE: For 1997 MY and earlier the pinion factor was a fixed value and cannot be changed with the DRB.
